Extracted text: Independent random samples, each containing 90 observations, were selected from two populations. The samples from populations 1 and 2 produced 78 and 70 successes, respectively. Test Ho : (P1 – P2) = 0| against H. : (P1 – p2) + 0ļ Use a = 0.06|. (a) The test statistic is (b) The P-value is (c) The final conclusion is A. We can reject the null hypothesis that (p1 – P2) = 0|and accept that (P – P2) + 0 B. There is not sufficient evidence to reject the null hypothesis that (p – P2) = q.
